IPC: G06F11/267
Filed: 1991-07-19
Abstract: INTELLIGENT DISK ARRAY CONTROLLER     BACKGROUND SURFACE ANALYSIS                     ABSTRACT A method for performing background disk sector Analysis for drives, including drives dedicated to redundancy and/or fault recovery techniques, in an intelligent, microprocessor based disk array.  The method directs the microprocessor to wait a specified time and test for disk activity.  In the absence of disk activity, the disk controller is directed to generate a read request for a disk memory location within the array.  A return code following the array is checked to determine if the read failed, indicating a disk drive media failure.  The disk controller is then notified if a failure occurs.  The processor again checks for disk array activity and in the absence of activity issues a read request for successive locations within the array, thereby reading all disk memory locations within the array.

Title: Passenger out-of-position sensor
Inventor: WHITE CRAIG W
IPC: B60R21/02
Filed: 1991-08-08
Abstract: PASSENGER OUT-OF-POSITION SENSOR                        ABSTRACT           A circuit for a actuating a vehicle passenger safety restraint such as an air bag includes pyroelectric sensors, pressure transducers, and ultrasonic acoustic sensors for sensing the presence, weight, and relative position of the passenger within a vehicle, respectively, which  information  is  supplied  to a  control  module controlling operation of the restraint.   The control module, which includes processor means, calculates the likely effectiveness of the restraint in preventing or otherwise mitigating injury to the vehicle passenger in the event of subsequent operation of the restraint.  A signal lamp is illuminated by the control module in the event that the passenger assumes a position which reduces the calculated likely effectiveness of the restraint below a threshold level therefore thereby warning the passenger of the heightened risk of injury. Preferably, the control module uses the information generated by the sensors to supplement or otherwise corroborate other information received from inertia-type "crash" sensors or frangible "crush" sensors, thereby ensuring operation of the restraint only in those instances where the passenger is indeed placed at risk.  Most preferably, the restraint is capable of providing a variable response, and the control module adjusts the response of the restraint prior to triggering the operation thereof so as to provide maximum protection to the passenger against injury.

Title: Turbine rotor seal body
Inventor: CHAMBERS STEPHEN M
IPC: F01D5/30
Filed: 1991-08-08
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for reducing thermal distress and creep of a disk post in a gas turbine engine, the disk post being defined between an adjacent pair of blade roots of a respective pair of turbine blades in a turbine disk.  The blade roots extend radially outward of the turbine disk and each terminate in a blade platform to form a cavity above the disk post. A seal generally covers the cavity for preventing a flow of combustion gases over the disk post.  The seal includes axial segments defining a channel over a radially outer surface of the disk post.  A flow of insulative air is directed into the channel defined over the disk post and diffused to reduce its velocity.  The insulative air effectively reduces heat transferred from the blade platforms and combustion gases to the disk post.
Patent CA-2051313-A1 (CA)
IPC: B65G33/20
Filed: 1991-09-13
Abstract: A screw conveyor with a slowly rotating feed screw for precision metering by conveying very small amounts of loose material between screw threads, the same amount of loose material being discharged from the end of the conveyor with eachturn of the screw. During the relatively short time interval of a single revolution, which can last one minute or even a multiple thereof as needed, the conveyor capacity itself fluctuates, since discrete amounts of the material being conveyed are always delimited by the individual threads of the feed screw. In order for a screw conveyor to be usable for precision metering of very small amounts to be conveyed, i.e. for conveying very small amounts with a high degree of constancy without the periodicity caused by the nature of the feed screw, the screw conveyor is provided with a rotatably mounted tube surrounding the discharge end of the fixed feed tube and which is driven at a rotational speed proportional to the rotational speed of screw.

Title: Field effect transistor
Inventor: NAKAJIMA SIGERU
IPC: H01L29/20
Filed: 1991-11-15
Abstract: In a prior art HEMT, when a high electric field is applied to the gate electrode, two-dimension electrons in the channel layer move to the electron supply layer and the high frequency characteristic is deteriorated. The present invention provides a field effect transistor in which a semiconductor layer having a thickness to spatially separate a two-dimension electron gas from doner ions of an electron supply layer and form two-dimension electron gas in a channel layer by a Coulomb force of the doner ions and having a better high frequency characteristic than that of the electron supply layer is formed between the channel layer and the electron supply layer.      In accordance with the present invention, when a high electric field is applied to the two-dimension electron gas and the energy of the electrons increase so that the electrons jump out of the channel layer, the electrons are moved to the semiconductor layer of the predetermined thickness having the good high frequency characteristic, which is adjacent to the channel layer. As a result, even if the high electric field is applied to the channel of the FET, the transport characteristic of the electrons is not deteriorated and the high frequency characteristic of the device is assured.

Patent CA-2061892-A1 (CA)
Title: Supplying fluid
Inventor: BOUCHER ROBERT F
IPC: G01F5/00
Filed: 1992-02-26
Abstract: A package burner has a fan rotatably driven at constant speed.  Air from the surrounding atmosphere is induced by the fan through an open end of a conduit which guides the air to the fan from which the air is propelled down an outlet passage to mix as combustion air in a chamber with fuel gas from a gas supply nozzle so that flames issue from the chamber.   A valve in the conduit or outlet passage can be set to regulate how much air is supplied as combustion air.  A fluidic oscillator has an inlet open to the atmosphere and has an outlet open to the interior of the conduit.  The observed frequency of the fluidic oscillator is a function of the flow rate of air through the fluidic oscillator and is also a function of the flow rate of air along the conduit.          Therefore the measured frequency of the fluidic oscillator can be used to calculate the amount of combustion air being supplied along the conduit in unit time.
